Nope, you could almost copy any pure C code, but you still need to add in the headers.

what i have to change to make this code run for C and not C++
Everything. You will have to rewrite your code from scratch if you want to make it C code.

can anyone suggest my a written C code for hangman with the same specifications as this one?
This is my project from my university I wrote the program to C++ and my fucking professor doesn't accept anything except C code. So I have to figure out something fast!

Just convert it from C++ to C, you are taking the class you should have the fundamentals down for c. We aren't going to do that for you.

Also, if your professor only accepts c why code it in c++ :P

Well for starters C will have different #includes, and almost 85% of your code will have to be rewritten. And the resulting C program will also be longer.

can anyone help me out and find what is wrong with that code?

You could ask your friend.

Go to the C forum...

Okay a friend of mine gave me this code.

Does that mean you plan to turn in plagarized code?

If you know C and C++, it's pretty straightforward to port this code to C, but you'll have to go through it line by line.

Did the professor specify C code up front? If not then I think you should argue the point with him/her. That would certainly be the path of least resistance. If they refuse to take the C++ program then ask for an extension based on the unclear directions and the fact that you have a working program. If the prof did specify C up front then ouch: consider it a valuable lesson in reading the instructions carefully.

i don't know C well, but you may try this:
you can use a 2d char array to store the words.
then using nested loop you can shuffle them.

you can also search c libraries:

It is not possible to change c++ to C code as it is. becaue there are different header files used in both languages. you can change code from c++ to C, but you need to make a small change in code.

in your friends code,
#include <string.h> is required to use strcpy() and the format used in strcpy is wrong, see correct format here: http://www.cplusplus.com/reference/cstring/strcpy/

use srand(time(NULL)); only once in your program.
RNG function is wrong. use res = rand()%(max-min+1) + min; instead.


another beginners thing: char ch[5]; allows you maximum 4 chars + null char at the end. but that code used [10] for 10 length string!!!

wow! i didn't know that C doesn't support bool b= true; !

I didn't know that C doesn't support bool b= true;

Of course it does, you just need to #include <stdbool.h> and make sure your compiler is not configured to use some prehistoric version of C (for gcc, I use -std=c11 or -std=c99)
